In the present work, O-O collisions at sNN=7TeV and p-O collisions at sNN=9.9TeV are studied using the PYTHIA8/Angantyr model for heavy-ion collisions. The theoretically predicted α-cluster structure of oxygen nucleus is implemented in the model to investigate the effect of the initial configuration of the oxygen nucleus on final state observables. The results obtained from the α-cluster structure are compared with those obtained from Woods-Saxon nuclear charge density distribution. The Angantyr model simulation showed that the radial distribution of the oxygen nucleus in α-cluster configuration is more compact in comparison to the Woods-Saxon distribution. The results on charged and identified particle pseudorapidity distribution are obtained in the two initial state configurations of the oxygen nucleus. The results demonstrated that the effect of initial geometrical configuration is more distinct in the noncentral collisions in comparison to the central collisions for both O-O and p-O collisions.
